Helloween, Gamma Ray, Hammerfall... if you're into traditional Power Metal, you should pay attention to Freedom Call. This German band emerged from the unknown in 1999 with the album Stairway To Fairyland. But with 2001's Crystal Empire, they really reached another level. Around their leader Crhis Bay , it's not surprising to find Daniel Zimmermann , the rhythm master of Gamma Ray. The line-up was completed by Sacha Gerstner and Ilker Erstin .
